Executive Snapshot and Market Trajectory.

Silicon carbide won the performance argument years ago and nobody serious disputes it. The commercial contest moved immediately to the wafer underneath, where crystal growth is slow, yield is poor, and whoever controls substrate supply controls how many devices anybody can actually ship. That is where the money is.
The market stands at USD 46.8 billion in 2025 and reaches USD 115.95 billion by 2036 at an 8.6% CAGR. Gallium nitride devices grow fastest at 28.2%, about 3.28 times the overall rate, from a base small enough that a handful of design wins moves the number. East Asia holds 30% of value on vehicle and industrial production, while India posts the quickest national growth at 15.2%.
Concentration is high, with the top five holding roughly 42% of power device revenue because qualification cycles and automotive reliability requirements both favour incumbents heavily. Two forces pull against each other. Electrification keeps adding power conversion stages to vehicles, chargers, and data centres, while Chinese silicon carbide capacity arriving at scale threatens the pricing that funded every Western capacity commitment made in the last five years. Capacity was committed before that arrived.

Power Semiconductor Market Forecast Scenarios

power-semiconductor-market-size-forecast-scenario-1787332618516
Growth from 2020 to 2025 compounded near 7.5%, and shortage rather than demand set the tone. Automotive semiconductor scarcity through 2021 and 2022 gave power device makers pricing power they had not held in decades, and long-term supply agreements were signed at terms nobody would have accepted before. Silicon carbide capacity was committed aggressively into that environment. Utilisation has since become the question rather than availability.
Three mechanisms carry the base case to 8.6%. First, vehicle electrification, where each traction inverter, onboard charger, and converter adds power device content that a combustion vehicle never carried. Second, data centre power conversion, as accelerator racks push power density to levels where conversion efficiency becomes a facility constraint rather than an engineering preference. Third, industrial drive and renewable inverter demand, which grows steadily with installed generation and motor efficiency regulation.
The bull case at 9.8% assumes silicon carbide adoption spreads beyond premium vehicles and gallium nitride captures data centre conversion at scale. The bear case at 7.4% assumes Chinese silicon carbide capacity resets pricing before Western plants recover their capital, electric vehicle volumes grow more slowly than platform commitments assumed, and industrial demand stays soft while manufacturing investment remains cautious across mature markets.

Substrate Supply Decides Who Actually Ships

Demand rests on three foundations. Electrification provides the content growth, since a battery electric vehicle carries power device value several times a combustion equivalent and every conversion stage adds more. Efficiency regulation provides the pull in industrial and data centre applications, where conversion losses become a facility constraint rather than a design preference. And substrate supply sets the ceiling, because silicon carbide crystal growth takes seven to 14 days and cannot be
MARKET CONCENTRATIONCR5: 42%Concentrated because automotive qualification favours established suppliers heavily
CRYSTAL GROWTH TIME7 to 14 daysBoule growth period before any wafering can begin
SUBSTRATE COST SHAREAbout 47%Wafer as a portion of finished silicon carbide device cost
AUTOMOTIVE QUALIFICATION TIMELINE3 to 5 yearsPeriod from design engagement to volume production release
DEVICE CONTENT PER VEHICLEUSD 90 to 750Power semiconductor value across combustion and electric platforms
CAPACITY UTILISATIONAbout 72%Running rate across qualified power device fabrication assets
Commercially the interesting number is how much of a silicon carbide device is the wafer. Substrate runs roughly 47% of finished device cost, which is unlike anything in silicon and explains why every serious participant has bought, built, or contracted crystal capacity. Utilisation near 72% across the industry meanwhile says capacity committed during the shortage arrived into a softer market than the commitments assumed.
The next decade turns on two questions. Whether Chinese silicon carbide capacity resets pricing before Western plants recover the capital committed during the shortage, which is a genuine risk nobody has priced. And whether gallium nitride at 28.2% growth converts data centre and charger design wins into volume, or stays a promising technology waiting for a platform that never quite commits to it.
"Everybody can explain why silicon carbide is better. Very few can explain how many defect-free 200 millimetre wafers they will have in 2029, and that second answer is the one that decides who is still in this business."

Market Trends

Vertical Integration Into Substrate Becomes The Real Strategy

Substrate is roughly 47% of finished silicon carbide device cost and crystal growth takes seven to 14 days that no capital expenditure shortens, which makes wafer supply the binding constraint rather than fabrication capacity. Every serious participant has responded by buying crystal growers, signing multi-year substrate agreements, or building boule capacity outright. The 200 millimetre transition raises the stakes further, since larger diameter improves device economics considerably while making defect-free growth harder. Device design differentiation matters far less than this. Nobody is winning this on device architecture any more at all.
Market Impact: Content rises toward USD 750

Automakers Now Contract Devices Directly Past Tier Ones

Vehicle manufacturers facing silicon carbide scarcity began signing long-term supply agreements and prepayments directly with device makers rather than leaving power semiconductors to a tier one inverter supplier. That relationship has largely persisted, which changes who holds the specification and who captures the margin across the traction inverter. Device makers now sit in vehicle architecture discussions three to five years before production. Tier one suppliers that treated power devices as a purchased component have found themselves negotiating around agreements they were not party to. That channel change shows no sign of reversing.
Market Impact: Racks draw 100 kilowatts each

Market Opportunities and Growth Drivers

Every Electrified Platform Adds Conversion Stages

A battery electric vehicle carries a traction inverter, an onboard charger, and multiple direct current converters where a combustion vehicle carried almost nothing comparable, which lifts power semiconductor content from roughly USD 90 to as much as USD 750 per vehicle. Charging infrastructure adds a further conversion stage outside the vehicle entirely. None of that content reverses once a platform is designed around it. This is the most predictable demand in semiconductors because it follows vehicle architecture rather than any consumer preference. Vehicle architecture rather than consumer preference fixes that content.
Market Impact: Utilisation sits near 72%

Data Centre Power Density Makes Conversion Efficiency Binding

Accelerator racks draw power at densities that turn conversion losses into a facility problem rather than an engineering preference, since every watt lost in conversion becomes heat somebody must remove. That has pulled gallium nitride and silicon carbide into power supply and rack conversion designs where silicon was adequate five years ago. Efficiency at partial load matters as much as peak, which favours wide bandgap devices considerably. Facility power constraints rather than component cost now drive these specification decisions. Component cost stopped being the deciding variable in any of these designs.
Market Impact: Qualification takes 3 to 5 years

Market Restraints and Challenges

Chinese Silicon Carbide Capacity Threatens Western Economics

Chinese substrate and device capacity has been built at a pace and cost base that Western plants committed during the shortage cannot match, and domestic vehicle manufacturers are qualifying it rapidly. The root cause is state-supported capital combined with a domestic demand base large enough to absorb early yield losses. Commercially this threatens the pricing every Western capacity commitment assumed. Participants mitigate through automotive qualification depth, long-term supply agreements signed before the capacity arrived, and moving toward 200 millimetre economics faster than competitors can. Nobody in the West has restated those investment cases.
Market Impact: Substrate is 47% of device cost

Automotive Qualification Excludes Entrants For Years

Power devices in a traction inverter must pass automotive reliability qualification, functional safety documentation, and platform validation running three to five years before a single unit ships in volume. The root cause is that a device failure in a traction inverter is a vehicle safety event rather than a warranty claim. Commercially this protects incumbents and makes entry expensive and slow. Newer entrants mitigate by starting in charging, industrial, and consumer applications where qualification is lighter, then carrying the process maturity into automotive later. Device performance alone does not shorten it.
Market Impact: Agreements run 3 to 5 years

Segment CAGR and Growth Architecture

Segmentation follows device technology, a single classification describing the semiconductor material and device structure. Each technology carries its own substrate supply, fabrication route, qualification burden, and cost position, so commercial economics track the device family rather than the application it serves. End-use industry and sales channel appear separately within the framework as their own distinct dimensions.
power-semiconductor-market-market-share-analysis-1787332619050

Gallium Nitride Devices

Gallium nitride devices grow fastest at 28.2%, about 3.28 times the overall 8.6% rate, from a base small enough that a handful of design wins moves the total. Switching speed and low losses at moderate voltage suit chargers, adapters, and increasingly data centre power conversion, where efficiency at partial load has become a facility constraint. Automotive traction remains largely silicon carbide territory because the voltage class favours it. Growing on silicon substrates keeps material cost far below silicon carbide, which is the segment's genuine commercial advantage. Reliability data at automotive duty cycles is still accumulating and that limits adoption. A handful of platform commitments would change that trajectory entirely and quickly.
CAGR 28.2%

Silicon Carbide Devices

Silicon carbide devices grow at 21.4%, the second-fastest technology and by far the largest contributor to absolute growth, because traction inverters at 800 volts run considerably more efficiently on them than on silicon. Substrate rather than device design is the commercial variable, since the wafer is roughly 47% of finished cost and crystal growth takes seven to 14 days regardless of capital available. The 200 millimetre transition improves economics substantially and makes defect-free growth harder at the same time. Chinese capacity arriving at scale is the pricing risk nobody in the West has fully priced yet. Device design differentiation counts for considerably less in this segment than wafer supply position ever does.

Regional Architecture and Country Demand Map

Vehicle and industrial production together set this distribution rather than semiconductor design activity. East Asia leads on manufacturing volume across vehicles, industrial equipment, and consumer electronics, while South Asia and Pacific grows quickest from a genuinely small installed base. Substrate access decides who can serve any of it.

North America

North America holds 22% of value, weighted toward data centre power conversion, industrial drives, and a vehicle electrification programme that has proceeded unevenly against announced targets. Accelerator rack power density has made conversion efficiency a facility constraint here first, which pulled gallium nitride into designs where silicon had been adequate. Federal semiconductor funding has directed attention toward power device and substrate capacity specifically. Wolfspeed built substantial silicon carbide capability domestically. Growth of 8.4% reflects data centre demand offsetting vehicle programme delays that have moved slower than platform commitments assumed. Substrate capacity built here during the shortage years is now recovering its capital considerably more slowly than any of the investment cases assumed.
Share: 22% | CAGR: 8.4% (2026 to 2036)

Western Europe

Automotive architecture rather than semiconductor manufacturing defines this market. Western Europe holds 23% of value, with German, French, and Italian vehicle platforms specifying silicon carbide traction inverters and European device makers including Infineon and STMicroelectronics holding genuinely strong global positions from here. Industrial drive and renewable inverter demand adds steady volume. Energy costs since 2022 have disadvantaged European fabrication against Asian and American plants on comparable devices. Growth of 7.0% is the slowest of the seven regions, reflecting flat industrial output and vehicle volumes that have not recovered to prior levels. Device makers headquartered here hold global positions that European fabrication cost alone would never have supported on its own.

Where Power Device Margin Is Defended

Competing on device specification when the wafer is half the cost misreads where this market is decided. The four moves below reach what actually matters: substrate control, automotive qualification depth, direct architecture access, and the 200 millimetre transition that resets unit economics for whoever completes it first. None of the four is a device specification argument.

Control Substrate Supply Or Accept Somebody Else's Ceiling

Wafer is roughly 47% of finished silicon carbide device cost and crystal growth takes seven to 14 days that no capital shortens, which makes substrate the binding constraint on how many devices anybody ships. Buying crystal growers, contracting boule supply on multi-year terms, or building capacity outright are the only three available answers. Device makers without one of them are quoting against a supply position a competitor controls. This decision has already separated the participants who will matter from those who will not. That decision has already been taken by the serious participants.
Market Impact: Substrate accounts for about 47% of

Complete The 200 Millimetre Transition Ahead Of Rivals

Larger diameter substrate improves die per wafer and device economics substantially, and it makes defect-free crystal growth considerably harder at the same time. Whoever completes that transition at acceptable yield first holds a cost position competitors cannot answer with pricing. The engineering is genuinely difficult and the capital is committed years before the benefit appears. Producers still optimising 150 millimetre processes are improving a platform their competitors intend to abandon, which is the least productive place to spend engineering effort. Capital committed today delivers the benefit only several years afterwards.
Market Impact: Larger wafers lift usable die count

Hold Automotive Qualification As An Entry Barrier

Traction inverter devices require automotive reliability qualification, functional safety documentation, and platform validation running 3 to 5 years before volume, because a failure there is a vehicle safety event rather than a warranty claim. That timeline excludes entrants from the highest-value application entirely regardless of their device performance. Incumbents should treat qualification depth as the asset it is rather than as a compliance cost. Entrants should start in charging and industrial applications and carry the process maturity across later. Nothing about having a better device shortens that timeline by a single quarter.
Market Impact: Automotive qualification runs 3 to

Sit In Vehicle Architecture, Not In A Purchase Order

Vehicle manufacturers began contracting power devices directly during the shortage and have largely kept doing it, which puts device makers in architecture discussions three to five years before production rather than in a tier one purchase order afterwards. The supplier present for that work shapes the inverter topology and is designed in by default. Tier ones treating power semiconductors as a purchased component are now negotiating around agreements they were never party to, which is a genuinely weak position. Agreements signed during the shortage still run 5 or more years out.
Market Impact: Architecture decisions precede prod

Who Controls the Margin Pool

Concentration is high: the top five hold roughly 42% of power device revenue, because automotive qualification, reliability data, and substrate access all favour established suppliers. The gap between leaders and challengers is wafer supply position and qualification depth rather than device design, which is widely understood. All participants here are assessed on one basis, revenue from power semiconductor devices, modules, and power management circuits, excluding logic and memory, substrates s
Competition runs along four lines. First, substrate control, since the wafer is roughly half of silicon carbide device cost. Second, automotive qualification depth, which gates the highest-value application entirely. Third, progress toward 200 millimetre economics, where the cost advantage will be decisive. Fourth, direct access to vehicle architecture decisions taken years before any sourcing package exists.

Pressure is building from two directions. Chinese substrate and device capacity has arrived at a cost base Western plants committed during the shortage cannot match, and domestic vehicle makers are qualifying it quickly. Meanwhile utilisation near 72% says the industry built for a demand curve that has not appeared. Rankings should favour suppliers with owned substrate and 200 millimetre progress over those defending device performance claims alone.

Competitive Moat and Risk Dimensions

INFINEON TECHNOLOGIES

Moat: Substrate contracts and automotive depth

Infineon secured multi-year silicon carbide substrate supply from several sources before capacity tightened, which addresses the constraint that actually limits shipment volume rather than the one competitors discuss. Its automotive qualification depth and direct relationships with vehicle manufacturers reach architecture decisions years before sourcing. Breadth across silicon, silicon carbide, and gallium nitride lets it supply a whole platform.
INFINEON TECHNOLOGIES

Risk: Capacity timing and Chinese pricing

Silicon carbide capacity was committed during a shortage into a market where utilisation now sits near 72%, which leaves fixed cost recovering more slowly than the investment case assumed. Chinese substrate and device supply competes at a cost base European fabrication cannot approach. Vehicle electrification volumes have also grown more slowly than the commitments underlying that capacity expected.
ONSEMI

Moat: Vertical substrate integration and focus

onsemi bought crystal growth capability outright rather than contracting it, which gives direct control of the input representing roughly 47% of silicon carbide device cost and of the yield learning that decides output. Its exit from lower-margin silicon lines concentrated capital on power and sensing where it competes seriously. Long-term supply agreements with vehicle manufacturers were signed before capacity tightened.
ONSEMI

Risk: Concentrated exposure and integration risk

Portfolio focus means silicon carbide demand disappointment reaches the whole business rather than one division, and vehicle programme timing has been consistently optimistic. Owning crystal growth transfers yield risk onto the balance sheet rather than onto a supplier. Chinese competitors with comparable integration and lower cost bases are qualifying into exactly the applications this strategy targets.

Recent Developments

JANUARY 2025

Silicon carbide substrate pricing falls as Chinese capacity ramps

Substrate pricing declined materially as Chinese crystal growth capacity reached volume output, compressing the input cost that Western device makers had committed capital against during the shortage years. This was market pricing movement rather than a transaction, and it altered the return profile on every capacity investment made since 2021.
Signal: Cheaper substrate helps every device buyer
SEPTEMBER 2024

Two hundred millimetre silicon carbide production advances toward volume

Several producers moved 200 millimetre silicon carbide wafer production from qualification toward commercial output, improving die per wafer economics while defect-free growth at that diameter remained genuinely difficult. These were capability milestones rather than transactions, and the cost advantage accrues entirely to whoever reaches acceptable yield first.
Signal: Whoever reaches acceptable yield at larger
MAY 2024

Vehicle manufacturers extend direct device supply agreements

Additional vehicle manufacturers signed multi-year power semiconductor supply agreements directly with device makers rather than leaving the component to tier one inverter suppliers. These were supply contracts rather than acquisitions, and they confirmed a channel change that began during the shortage and has not reversed since.
Signal: Direct contracting moved specification aut

Silicon Carbide Substrate, Silicon Wafers, Energy, Packaging

Cost structure differs completely between silicon and wide bandgap devices. Silicon carbide substrate runs roughly 47% of finished device cost, which is unlike anything in conventional semiconductors. Epitaxy adds 12% to 18%, front end processing 14% to 22%, and packaging with sintered die attach and advanced interconnect a further 12% to 20%. Silicon device cost by contrast sits mostly in processing rather than in the wafer.
European energy prices through 2022 hit crystal growth and epitaxy particularly hard, since both run long high-temperature cycles that cannot be interrupted economically, with IEA analysis recording industrial gas at several times prior-year levels. Infineon and STMicroelectronics both disclosed energy and input cost pressure across that period. Substrate pricing then moved the other way as Chinese capacity ramped, which helped device cost and damaged substrate investment returns simultaneously.

Exposure separates by substrate position rather than by fabrication scale. A device maker owning or contracting crystal growth controls roughly half its cost and its output ceiling together, while one buying substrate on the merchant market carries whatever that market does and cannot ship beyond what it is allocated. Geography compounds it, since Chinese producers combine integrated substrate with lower energy and capital costs.
power-semiconductor-market-cost-volatility-analysis-1787332620304

Secure substrate through ownership or multi-year contract

Wafer is roughly half of silicon carbide device cost and crystal growth cannot be accelerated with capital, which makes substrate position the single most consequential commercial decision a device maker takes. Ownership transfers yield risk onto the balance sheet while contracting leaves it with a supplier. Both beat buying merchant, which caps output at whatever somebody else sells.

Move epitaxy in house to capture yield learning

Epitaxial layer quality determines device yield more than most front end steps, and outsourcing it separates the learning from the party that needs it. Bringing epitaxy inside links substrate quality, layer growth, and device yield into one improvement loop. The capital and process development are substantial, which is why several device makers deferred it too long.

Design packages for the thermal envelope wide bandgap allows

Silicon carbide and gallium nitride run hotter and switch faster than silicon, and a package designed for silicon wastes much of that advantage in parasitic inductance and thermal resistance. Sintered die attach, advanced substrates, and low-inductance layouts recover it. Package development is unglamorous against device physics and it frequently delivers more system-level benefit than the next die shrink does.

Portfolio Architecture for Margin Defence

The portfolio splits into three tiers with different economics. Standard silicon diodes and discretes form the volume tier, where the design is mature and nothing differentiates one part from another. Silicon insulated gate bipolar modules and power management circuits earn more because thermal design narrows the field. Silicon carbide and gallium nitride devices price against substrate scarcity and qualification depth rather than against a competing part number.
The tension runs between silicon volume that fills the fab and wide bandgap devices that carry the growth. Silicon discretes and modules keep mature fabrication loaded, cover depreciation on written-down equipment, and hold the relationships through which wide bandgap qualification arrives. Yet they compete against Asian suppliers on cost that Western fabs cannot reach. Producers handling this well run silicon for utilisation while directing capital toward substrate capability.

High-value pools concentrate where substrate or qualification limits competition: silicon carbide traction devices qualified into platforms, gallium nitride in data centre conversion, high-voltage modules for grid and traction, and any device where the producer controls its own wafer supply. All four escape the part number comparison. Standard silicon diodes sit at the other end, where a dozen suppliers meet the datasheet and price decides.

Volume / Commodity-Adjacent Tier

Standard silicon diodes, discrete transistors, and mature power management parts sold on price against many suppliers. The range is wide because fab depreciation status and regional energy cost separate producers enormously at identical selling prices.
Gross Margin: 20-34%

Premium / Certified Tier

Silicon insulated gate bipolar modules, automotive-qualified silicon devices, and application-specific power management circuits. The range is wide because automotive qualification protects some parts far better than others and thermal design capability varies sharply.
Gross Margin: 34-50%

Sustainability / Regulatory / Next-Generation Tier

Silicon carbide traction devices, gallium nitride conversion parts, and 200 millimetre substrate-backed production. The range is wide because substrate position decides cost while newer technologies still carry unrecovered qualification and capacity cost.
Gross Margin: 38-58%
power-semiconductor-market-portfolio-architecture-1787332620804

High-value Sub-segments and Strategic Watch-out

Gallium Nitride Devices

High value and high growth at 28.2%, the fastest technology, on chargers, adapters, and data centre conversion where switching speed and partial load efficiency matter most. Growing on silicon substrates keeps material cost far below silicon carbide, and automotive reliability data is still accumulating. Volumes remain small for now.
Gross Margin: 38-58%

Silicon Carbide Devices

High value with strong growth at 21.4%, the largest contributor to absolute growth on traction inverters at 800 volts. Substrate rather than device design is the commercial variable, and Chinese capacity arriving at scale is the pricing risk nobody has fully priced. Substrate decides everything here.
Gross Margin: 36-56%

Silicon IGBTs and Modules

The volume core by revenue, growing at 5.6% across industrial drives, traction, and renewable inverters where the voltage class and cost still favour silicon. Thermal design and module construction remain genuine differentiators that a datasheet comparison never captures. A datasheet comparison misses almost all of it.
Gross Margin: 30-46%

Silicon MOSFETs and Diodes

The strategic watch-out, growing at 4.4% and squeezed between Asian cost bases below and wide bandgap substitution above. Volume remains enormous across consumer, automotive, and industrial applications, but nothing about the part is defensible. Wide bandgap substitution keeps taking the better applications away from it first.
Gross Margin: 20-34%

How Device Design Wins Actually Hold

Demand commits at design-in and repeats for the platform life. A power device qualified into a traction inverter has passed reliability testing, thermal validation, functional safety review, and often a field trial, and nobody reopens that inside a platform generation without a supply failure. That protects incumbents for seven to ten years. The genuine competitive moments are a new vehicle architecture, an inverter redesign, and any substrate shortage stopping an incumbent delivering.
Stickiness varies by qualification depth and safety consequence. Automotive traction devices stick hardest, since requalification touches a vehicle safety case nobody reopens casually. Industrial modules stick nearly as firmly through thermal and mechanical fit in an existing enclosure. Data centre conversion parts stick through efficiency validation. Standard silicon discretes stick least, moving on price at every purchase because a dozen suppliers meet the same datasheet exactly.

Buyer profiles have moved from tier one purchasing teams comparing part prices toward vehicle architects, facility power engineers, and supply security functions holding decisive input. Vehicle manufacturers now contract devices directly rather than delegating them. That change rewards suppliers bringing substrate security, qualification evidence, and architecture engagement, and penalises those still presenting datasheet performance to a buyer who no longer decides.

Our Call On Power Semiconductors

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / SUBSTRATE POSITION PRIORITY

Half your cost and all your ceiling sit upstream

Wafer represents roughly 47% of the finished silicon carbide device cost and crystal growth takes seven to 14 days that no amount of capital can shorten, which makes substrate the binding constraint on shipment volume rather than any fabrication capacity. Owning crystal growth, contracting boule supply on multi-year terms, or building capacity outright are the only three answers actually available. A device maker buying merchant substrate is quoting against an output ceiling that somebody else controls entirely, quarter after quarter.
02 / LARGER WAFER TRANSITION

The cost advantage goes to whoever yields first

Two hundred millimetre silicon carbide wafer improves die per wafer and overall unit economics substantially while making defect-free crystal growth considerably harder to achieve, which is exactly why the resulting advantage is durable rather than temporary. Whoever reaches acceptable yield at that diameter first holds a cost position competitors cannot answer with pricing or with device design. Producers still optimising 150 millimetre processes are busy improving a platform that their serious competitors fully intend to abandon entirely within this decade.
03 / ARCHITECTURE STAGE ACCESS

Vehicle makers now contract devices past the tier one

Vehicle manufacturers facing silicon carbide scarcity began signing supply agreements directly with device makers, and they have largely kept doing so, which puts device suppliers in vehicle architecture discussions three to five years before production. The supplier present for that work shapes the inverter topology and is designed in by default when the programme finally ramps. Tier ones that had treated power semiconductors as a purchased component now find themselves negotiating around agreements they were never party to at all.
04 / CHINESE CAPACITY EXPOSURE

Price the risk nobody has written down yet

Chinese substrate and device capacity has been built at a pace and cost base that Western plants committed during the shortage simply cannot match, and domestic vehicle manufacturers are qualifying it rapidly. Utilisation near 72% already says the industry built for a demand curve that has not arrived on schedule. Investment cases written on scarcity pricing between 2021 and 2023 are still carrying an assumption that has quietly stopped being true, and remarkably few of them have restated it since.

Power Semiconductor Producer Strategic Portfolio Review and Transition Roadmap 2026·Investment Scenario on Power Semiconductor Exposure Evaluation 2025-26
CLIENT PROFILE
A tier one traction inverter supplier with roughly USD 2.8 billion in annual revenue engaged MMA after two vehicle manufacturer customers contracted silicon carbide devices directly, leaving it assembling inverters around parts it no longer purchased. The client reported losing device margin on about 61% of its inverter volume and no substrate visibility whatsoever (client-reported, unverified by MMA).
STRATEGIC CHALLENGE
Recovering the device relationship meant competing with customers who had already signed multi-year agreements, while accepting the change meant becoming an assembler on assembly margin. Engineering wanted to design its own power module, and finance questioned whether that made any sense at current volumes. The board needed a position before the next platform sourcing round.
MMA APPROACH
MMA modelled inverter margin with and without device content rather than treating the two as one number, which internal reporting had never separated. We assessed whether module-level design and thermal integration could recover value that device pass-through had lost. We then examined substrate availability underlying each device supplier, since the client had no view of what actually constrained its own supply chain.
KEY FINDINGS
  1. Assembly-only inverter margin ran roughly 8 points below the historic blended figure, which meant the channel change had already cost more than any pricing negotiation ever had (client-reported, unverified by MMA).
  2. Module design and thermal integration were worth considerably more than device resale margin had been, and no competitor was contesting that ground seriously.
  3. Two of the client's four device suppliers had no owned or contracted substrate position, which made their delivery commitments considerably less reliable than assumed.
  4. Vehicle manufacturers contracting devices directly still needed module and thermal expertise the client held, and had not realised they were separable until it was pointed out.

  2. Module design and thermal integration were worth considerably more than device resale margin had been, and no competitor was contesting that ground seriously.
  3. Two of the client's four device suppliers had no owned or contracted substrate position, which made their delivery commitments considerably less reliable than assumed.
  4. Vehicle manufacturers contracting devices directly still needed module and thermal expertise the client held, and had not realised they were separable until it was pointed out.
RECOMMENDED STRATEGY
Phase 1: Phase 1 (0 to 6 months): Stop competing for device supply and reprice inverter work on assembly and integration content explicitly. Phase 2: Phase 2 (6 to 18 months): Build module design and thermal integration into a chargeable engineering service rather than a bundled cost. Phase 3: Phase 3 (18 to 30 months): Qualify only device suppliers with owned or contracted substrate and drop the two without it.
OUTCOME
The client stopped defending device margin it had already lost and rebuilt pricing around module and thermal integration, which recovered roughly two thirds of the gap within two years. Restricting qualification to substrate-backed suppliers also removed a delivery risk that had not previously been visible to anybody internally (client-reported, unverified by MMA).
